• ♦X: takeout for minors or could be 13-15 balanced
• ♦2♥: t/o minors more distributional
• ♦2♠: natural 6+
• ♦2NT: 15-18

• ♦X penalty, then next X is takeout, X after that is penalty again
• ◦2♣ scramble
• ◦2♦♥♠ natural
• ♦Also penalty, (1NT)-p-(2x)-X, so 15+ balanced

• ♦X for majors, NT for minors
• ♦If we bid at 1-level, 2♣ advance is natural, 1NT is cue bid

(e.g. 1♣-1♥ for spades by opponents)

• ♦X shows the suit they bid (in this case would show 5+ hearts)
• ♦Bidding their transfer suit is takeout (in this case bidding spades)
